An electrosurgical system for sealing tissue includes electrosurgical bipolar forceps and an electrosurgical generator. The electrosurgical bipolar forceps includes a shaft member having an end effector assembly disposed at a distal end. The end effector assembly includes jaw members movable from a first position in spaced relation relative to one another to a subsequent position. The jaw members are adapted to cooperate to grasp tissue therebetween. The jaw members each include a sealing plate that communicates electrosurgical energy through the held tissue. The gap sensor is adapted to sense the gap distance between the jaw members. The electrosurgical generator is operatively coupled to the electrosurgical bipolar forceps and generates the electrosurgical energy. The electrosurgical generator is in operative communication with the gap sensor and monitors a sensed gap distance therefrom. The electrosurgical generator generates the electrosurgical energy based on the sensed gap distance as a function of time.

A seal system for an intersection between a turbine stator and a turbine rotor to seal cooling fluids.

Method and apparatus for lowering capacitively-transduced resonator impedance within micromechanical resonator devices. Fabrication limits exist on how small the gap spacing can be made between a resonator and the associated input and output electrodes in response to etching processes. The present invention teaches a resonator device in which these gaps are then fully, or more preferably partially filled with a dielectric material to reduce the gap distance.
